How to use Image Resizer
Resizing changes pixel dimensions rather than merely changing display size. Smaller dimensions reduce transfer and storage needs, while enlarging cannot invent missing detail.
Steps
- Choose an image.
- Enter the required width or height.
- Select a format and download the resized copy.
Formats, limits, and accuracy
Keep aspect ratio enabled for photographs and logos unless a stretched result is intentional. The browser limits the largest canvas based on device memory.
Frequently asked questions
Can I resize by percentage?
Enter dimensions calculated from the original size shown after selection.
Does resizing crop the image?
No. The complete image is scaled to the new dimensions.
Practical notes
Exact pixel dimensions are useful for CMS and marketplace upload requirements.
Use an image cropper when the target aspect ratio must change without stretching.
